Abstract
Background

Vitiligo is associated with medical conditions, primarily autoimmune disorders; however, only a few studies in the United States have investigated these associations.

Objective

Our purpose was to investigate the diseases associated with vitiligo in the New York, New York, population and evaluate if these associations differ by race/ethnicity and sex.

Methods

In this retrospective study, we analyzed data collected from the medical records of 1487 vitiligo patients seen at New York University during a 10-year period.

Results

Vitiligo patients had a statistically significant higher prevalence of hypothyroidism, multiple sclerosis, rheumatoid arthritis, idiopathic thrombocytopenic purpura, seronegative arthritis, pernicious anemia, myasthenia gravis, inflammatory bowel disease, lymphoma, and systemic lupus erythematosus. Rates of comorbid autoimmune diseases varied by race and sex.

Limitations

Medical charts did not consistently report race/ethnicity, type of vitiligo, and total body surface area affected. Information from nondermatology medical visits was also included.

Conclusion

This study revealed multiple new disease associations for vitiligo, including multiple sclerosis, idiopathic thrombocytopenic purpura, and lymphoma, as well as confirmed previously reported associations with other autoimmune diseases, the most common being hypothyroidism followed by rheumatoid arthritis. Associations did vary by race/ethnicity and sex.
